Maxillofacial Rehabilitation Using Motor Imagery vs Sham After Orthognathic Surgery
Sponsor: Hospices Civils de Lyon
Summary
Dento-maxillary dysmorphoses are defined as an anomaly in the relative growth of the maxilla and/or mandible. They lead to functional disorders (i.e., disturbances in chewing or oral communication) and aesthetic issues with psychological repercussions on self-esteem, affecting the quality of life of these patients. The multidisciplinary treatment involves orthodontics (duration = 18-24 months), orthognathic surgery involving the maxillary and/or mandibular bone (at 12 months), immediately followed by physiotherapy (duration = 3 months). One main goal after surgery is the recovery of month opening to restore an appropriate orofacial function. Motor imagery (mental rehearsal of a movement without actually moving) is effectively used in athletes and in rehabilitation mainly neurological but so far has not been investigated in maxillofacial rehabilitation. Considering that the effectiveness of rehabilitation is increased when physical and mental practices are combined, this leads to propose this study aiming to investigate whether the addition of motor imagery of the maxillofacial region to maxillofacial physiotherapy (based on a practice of physical therapeutic exercises) modifies the recovery of maximum mouth opening, other ranges of motion, jaw function, and quality of life in patients after orthognathic surgery compared to the addition of a control cognitive task \[watching a non-emotional content film or filling out a crossword or Sudoku grid\] to maxillofacial physiotherapy.

Interventions
Motor imagery of the jaw
Fifty individuals who have undergone orthognathic surgery of the mandible alone or concurrently with the maxilla will be randomly assigned to the experimental group, which involves practicing motor imagery in addition to a self-rehabilitation program and physiotherapy. Patients will be guided to visualize three sets of jaw movements three times a day. Adherence to the program will be monitored by the physiotherapist. The program has been standardized across all participating centers as the study is multicentric.
Control task (Sudoku or Crossword puzzle)
Fifty individuals who have undergone orthognathic surgery of the mandible alone or concurrently with the maxilla will be randomly assigned to the control group, which involves practicing a control task (completion of Sudoku or crossword puzzles) in addition to a self-rehabilitation program and physiotherapy. Patients will be instructed to engage in the task for approximately 10 minutes per day, equivalent to the duration of motor imagery practice in the group 1. Adherence to the program will be monitored by the physiotherapist. The program has been standardized across all participating centers, as the study is multicentric.
